Construcción e implementación de un banco didáctico de un sistema de climatización HVAC para la escuela de ingeniería Automotriz

Abstract

It has built and implemented a HVAC training bench for the school of Automotive Engineering, in order to provide comfort conditions for temperature, humidity and clean air in the vehicle at the same time be used as a learning tool for develop skills in applications in the system. Analyzing the performance and technical characteristics of the climate control elements a component selection was made, based on fundamental parameters such as temperature delivery, efficiency and cost. After the selection of the elements of each system, these ones were selected: an electric heater and two fans; while the air conditioning system was incorporated: and electric motor, a transmission, band, compressor, capacitor, filter-drier, thermal expansion valve, evaporator, electric fan, air impeller, pipes, gauges and battery. In addition, the training bench has an electric hand control of 12 and 110 volts designed in specific software. The construction of the structure, location and assembly of parts and system mentioned above, was tested for operation as pressure for leak, vacuum, charge with refrigerant storage fluid, power testing, overload, finally tests temperature. With the implementation of this training bench comfort temperatures have been gotten considered between 20 and 22 C, provided by the heating system in a time of 60 seconds at maximum efficiency is obtained while the air conditioning system takes 10 seconds with pressures 30 and 150 Psi in the circuits of low and high pressure respectively, for this system is recommended as new refrigerants such as R-1234yf because it is very ecological.
